MILK-COOLER.

SPECIFICATION forming part of Letters Patent No. 753,699, dated March 1,1904.

Application filed May 12, 1903. Serial No. 156,733. (No model.) 7

To all whom it may concern:

Be it known that we, JOSEPH HADALLER and MARIA HADALLER, citizens of theUnited States, residing at Efiingham, in the county of Effingham, Stateof Illinois, have invented certain new and useful Improvements in Milk-(loolers; and we do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to milk-coolers; and

it has for its object to provide a machine which will cool the milk to amaximum degree in a.

I a milk-cooler embodying the present invening it, the gear and pinionbeing arranged interior to the casing.

Through the side of the casing adjacent to the'shaft 7 is anair-intakefll, through which may pass air to the fan, the air beingdischarged from the fan at the periphery thereof.

Above the fan is an arc-shaped plate 12, which extends concentricallywith the fanwheel from one side of the center of the wheel around thewheel and downwardly into the casing to a point at the same height withthe shaft 7, the side edges of the plate 12 being slightly raised toform a trough. Supported at the upper end of the plate or trough 12 ising downwardly in spaced relation to the trough 12 and then transverselybeneath and beyond the fan-wheel, the endof' the trough projectingthrough the side of the casing. With this position of trough 15 it willbe seen that it will receive from the trough 12 and convey the milkaround beneath the fanwheel and finally discharging it to a bucket orother receptacle 16.

It will be noted that the milk runs on the a hopper 13, which is spacedslightly above convex side of the trough 12 and on the concave side ofthe trough 15 and that when the fan is rotated the air will be forcedover the surface of the milk in the trough l5 and then upwardly againstthe bottom of the trough 12 and will finally be dischargedbetween theupper end of the trough 12 and the side of the casing, it being notedthat the wall of the casing is extended upwardly to touch that portionof the trough 12 which extends above the main body portion of thecasing.

With the present construction it is found that the milk is freshened andby reason of passing in a thin or shallow stream through the troughs isquickly reduced in temperature to the desired degree.

In practice modifications of the specific construction shown may be madeand any suitable materials and proportions may be used for the variousparts without departing from I the spirit of the invention.

What is claimed is a v 1. A milk-cooler comprising a fan, a troughpartly encircling the fan and disposed to carry milk exposed toair-currents from the fan, a second trough disposed above the fan andarranged to discharge into the first-mentioned trough, and a hopperhaving discharge-openings leading to the second trough.

2. A milk-cooler comprising a casing, a rotary fan mounted in the casingand adapted to discharge air at its periphery, an arc-shaped trough,disposed Within the casing, extending from its top and passing aroundbeneath the fan, a second arc-shaped trough, inverted in respect to thefirst-named trough, disposed Within the casing, extending from a pointbelow the top of the first-named trough, and

spaced therewith, and passing around above the fan, and a hoppersupported above the second arc-shaped trough.

3. A milk-cooler comprising a casing, a rotary fan mounted in the casingand adapted to discharge airat its periphery, an arc-shaped trough inthe casing passing around beneath JOSEPH HADALLER. MARIA HADALLER.
